verbose: Print messages conditional on the verbose level

Description

The verbose level can be represented by non-negative integers. The larger the number is, the more verbose is the program: it prints then more messages for users' information.

Usage

verbose(..., global = 1L, this = 1L)

Arguments

…

Messages to be printed, will be passed to the message function

global

Integer, the global verbose level

this

Integer, the verbose level of this message

Value

The function is used for its side effect by printing messages.

Details

This function decides whether or not to print a message, dependent on the global verbose level and the specific level of the message. If the specific level is larger than the global level, the message is suppresed; otherwise it is printed. see the details section for an example.

Suppose the global verbose level is set to 5, and two messages have levels of 1 and 7 repsectively. Since 1 suggests a low-threshold of being verbose, the first message is printed; whereas the message of level 7 is only printed when the program should run in a more verbose way (7,8,9,…{}), it is suppressed in the current global verbose level.

Examples

# NOT RUN {
Gv <- 5L
verbose("Slightly verbosing", global=Gv, this=1L)
verbose("Moderately verbosing", global=Gv, this=5L)
verbose("Heavily verbosing", global=Gv, this=9L)

# }
